Start by disconnecting everything from all those plugs.......one at a time to find out what is tripping it. My guess is that is may be the microwave. IF none of those seem to be an issue, check the lead out of the load center and be sure that there IS power to that circut. It won't reset without it. And possible that the GFCI is toast and needs replacing. Let me know if we need to dig deeper into this as all follow ups are included in our fee.
